At this point are you getting worried about the release of the BW concert dvd? lol..no ? why would I be..? if they are to release one they will, if not they won't. me being worried won't change the facts. :p
Do you think they will release one? most probably. and yes, one. :p last year we got two because of reasons..but I expect(and hope!) it won't happen again.
When do you think it will be released? well..that depends on the content obviously..most (Arashi) concert dvds take 5-8 months to edit, so it could be any time from April(if Kokuritsu) till June(if Dome)?
Which venue/s do you think will be included? now that's tricky..Kokuritsu's both days had rain and various (noticeable and unnoticed?) mishaps and the tour Final had..well we all know what :p and getting a dvd with that *on* it are probably minuscule. + various other dates(including the final?) were deemed dvd-camera less in fan reports..so long story short, God knows. :p Anything would be good though.
About the extras, will it have some? They're not really important on concert dvds, so who cares. They're good and appreciated...but they are not necessary. :p
Do you think Jun and/or Arashi are directly involved in the edition of the dvd? Jun probably/definitely is. I think he has mentioned it either on Enjoy or JunStyle before.
Which other releases do you expect during 2012? At least 2 more singles by the end of the year (I hope they pull a Spring 2009 with the 2 April dramas though D: or a double-A. otherwise it'd be too much of an overkill. they *don't* need to make a theme song every. single. time for every. single. renzoku drama D: of course most people don't seem to understand that).. Then probably a new album( in the second half of the year?) and of course dvd boxes/ dvds for this years series/sps (Lucky Seven box, here I come! :3)
..and I wouldn't want to lose hope just yet, but Aa Kouya's dvd was a lost cause the second the butai was announced. :p
